Abstract

There is a type of distance-regular graph, said to be QQ-polynomial. In this paper we investigate a generalized QQ-polynomial property involving a graph that is not necessarily distance-regular. We give a detailed description of an example associated with the projective geometry LN(q)L_N(q).
